[PATCH] D42133: [AArch64] Improve code generation of vector mask build

The case you implemented looks sensible, but I wonder if this can be implemented more generically so that the pattern can be used for other constants as well. Maybe it can be done using a ComplexPattern that encodes any (by MOVI encodable) constant as an immediate+shift and then uses those as input to MOVI. Is this something you have considered?
